12. To see the amount of dislocation, place the mechanism upside-down.
If the stopper bend has been dislocated in the direction of the first
CD, turn VR802 to the left(Fig. 2).
To lower the stage toward the twelfth step by 0.1 mm, reduce the
voltage of EREF (adjusted in step 8) by 10 mV.
If the stopper bend has been dislocated in the direction of the twelfth
CD, turn VR802 to the right(Fig. 4).
To raise the stage toward the first step by 0.1 mm, increase the volt-
age of EREF (adjusted in step 8) by 10 mV.
13. Place the mechanism horizontal. Go back to step 11 to reconfirm the
stage height.
14. When adjustment of the stage height is completed, proceed as fol-
lows:
15. Press the EJECT switch.
16. Once operation of the mechanism has stopped, turn the power OFF.
17. Wait more than one minute after the power is turned off, then turn the power ON and insert a magazine.
18. Check if the mechanism operates correctly with the first, sixth, seventh and twelfth CDs.
19. If the mechanism operates properly, adjustment is completed. If the mechanism operates improperly, make the
adjustment again.
